Meet the 2016 Shelby GT350 “HPE800” by Hennessey Performance Engineering – a serious contender for the title of “most epic pony car ever imagined.”

Hennessey Performance’s HPE800 upgrade for the 2016 Ford Shelby GT350 Mustang takes the track-oriented performance fastback from engaging plaything to absolute supercar by bolting a 2.9-liter supercharger onto the factory Voodoo V8. New, forged aluminum pistons and forged steel rods reduce the compression ratio from 12:1 to 11:1, and an upgraded fuel system, high-flow carbon fiber intake, and engine management calibration all work in concert to make it work.

All things considered, Hennessey claims that the Shelby GT350 with HPE800 upgrade package will put out around 808 horsepower, with 657 lb-ft of torque – enough for a 3.3-second 0 to 60 time, and a 10.8-second quarter-mile at 133mph.

Now, Hennessey has shared the above video, which shows a dynamometer test with the 2016 Shelby GT350 HPE800. The plot shown at the end reveals a leap in rear-wheel horsepower from 479 to 680 – the latter of which corresponds to about 800HP at the crank, assuming the standard 15 percent drivetrain loss.

Hennessey Performance Engineering is only offering a total of 50 HPE800 upgrade packages for the 2016 model year Shelby GT350, so you’d better snatch yours up quick.
